BOOKBINDIN G.

Application led October 16, 1916.

T0 all 'whom t may concern.

Be it known that I, FREDERICK J. Mo- MANN, a citizen of the United States, residing at Marinette, in the county of Marinette, State of Wisconsin, have invented certain new and useful Improvements in Bookbind* ing; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention belongs to the class of book binding, and has particular reference to an improved method of making books.

The object of the invention is to construct a book in such a manner that a stronger and more durable book is provided than any which are known to me. In the present invention the leaves of each signature or section are united adjacent to their inner edges by stapling or sewing as indicated, or in any other desired manner. Then, a plurality of strips of tape or other securing means is passed through the signature on the line of union of the leaves, the ends of the strips being eventually secured in the cover boards. This arrangement results in a secure and durable binding.

With the above objects in view and such other objects as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a horizontal section through a book between two sections or signatures,

Fig. 2 is a section on line 2 2 of Fig. 1,

Fig. 3 is a perspective view of one of the signatures showing the binding tapes passed therethrough, the signatures being stitched, an

Fig. 4 is a view showing the assemblage of a number of sections upon the tapes, the signatures being stapled or wired.

Referrin more particularly to the drawings, 1 indicates a section or signature of usual form which is stitched or wired to form a binding line 2 along its rear edge. When the section is stitched, as shown in Fig. 3, a plurality of slots or openings 3 are punched through the signatures just in front of, or just behind the line of stitching, whichever may be most convenient or desirable. Through the openings 3 are strung the tape strips 4, in a well-known manner, the

strength of the tapes depending upon the thickness of the books. Where the tapes are passed through openings formed in front of the line of stitching, the latter, obviously, forms a reinforcement through the sections 4 preventing the tapes from being torn out of the sections.

After the required number of sections and sheets have been strung upon the tapes 4, so as to form a book, it is rounded and backed in the usual manner and a heavy piece of cloth or other suitable material is glued firmly to the backs of the sections. The ends of the cloth, and the ends of the tapes are then secured to the boards which form parts of the book covers. Preferably, the tapes are carried inside of the boards and below the ends of the cloth backing, this and the remaining steps in the binding being carried out according to well-known binding methods. Itis obvious that in place of the woven tape 4, any other suitable ilexible material may be employed.

When the leaves of the sections or signatures arebound by means of the wire staples 5, they may be so spaced that the openings 6 may bo formed therebetween in direct line with the line of stitching so that the tapes may be located in this line.

What I claim as my invention is l. A book comprising a plurality of sheets folded on themselves to provide a group of leaves, a stitching contiguous to the line of fold of the sheets to bind the leaves together, said sheets being formed with openings punched therethrough, tapes passed through the openings, and cover boards having the ends of said tapes secured thereto.

2. A book comprising a plurality of sections, each formed from a series of sheets folded on themselves to provide leaves, means extending the whole length of the folds of the sheets for securing the leaves together, said leaves having openings punched therethrough adjacent to said securing means, flexible tapes passed through said openings to assemble the sections into a book, and cover boards having the tapes secured thereto.

In testimony whereof, I affix my signature, in the presence of two witnesses.

FRED. J. -MoMANN.
